This paper examines the role of uncertainty shocks in a one-sector, representative-agent dynamic stochastic general equilibrium model. When prices are flexible, uncertainty shocks are not capable of producing business cycle comovements among key macro variables. With countercyclical markups...

Business cycles in emerging markets are characterized by strongly counter-cyclical current accounts, consumption volatility that exceeds income volatility, and dramatic “sudden stops” in capital inflows. These features contrast with those of developed, small open economies and highlight the...

A two-sector real business cycle model, estimated with postwar U.S. data, identifies shocks to the levels and growth rates of total factor productivity in distinct consumption- and investment-goods- producing technologies. This model attributes most of the productivity slowdown of the 1970s to...

Lucas (1976) criticized Keynesian models because of parametric instability. For many economists, the "Lucas critique" provided a reason to replace the Keynesian approach with equilibrium models of the business cycle. One example of the equilibrium approach is the Real Business Cycle (RBC) model....

During the last few decades, labor markets in advanced economies have become “polarized” as relative labor demand grows for high- and low-skill workers while it declines for middle-skill workers. This paper explores how polarization has interacted with the U.S. business cycle since the late...

The appropriate role for equity prices in monetary policy deliberations has been hotly debated for some time. Recent work suggests that equity prices have affected monetary policy decisions above and beyond their indirect effect on the traditional goal variables of the FOMC. However, the...
